Yes it was what I had in mind, Although I'd say that any finger ring will give you inaccurate heart rate data when doing any kind of movement, including oura ring. These device are basically useful for one thing :monitor HRV while sleeping and maybe resting heart rate. That's all. Both can be done manually and more accurately at wake up with an app like elitehrv and polar H10 chest strap. I tried it, I tried the whoop, I tried many different brand sport watch. At the end of you remove the gimmicky feature these fitness device are all quite similar.
